In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this introductory textbook chapter, energy is defined and its sources, forms, and flow are introduced. Students are introduced to the first law of thermodynamics, conservation of energy. The resource includes links to current news articles, and a... (View More)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

This textbook chapter describes the processes through which El Niño and La Niña conditions emerge. The resource includes an animation of ocean currents, and links to current news articles, and a suite of pre- and post-unit assessments. A teacher's... (View More)

In this textbook chapter, students review concepts of matter and energy as a precursor to understand how carbon dioxide traps heat in the atmosphere. This is the second chapter in the unit, Climate Change, which addresses the question of how human... (View More)

In this textbook chapter, students are introduced to the study of tectonics through an exploration of the 1980 eruption of Mt. St. Helens, including an interview with geomorphologist Dr. Danny Vaughn, Indiana State University. The flow of energy,... (View More)
